[Grammar] Sentence transformation - causative or...?

[aleksije]

Hello to everybody. My nephew had homework on sentence transforming. One of the sentences was:

My mum cleaned my room.

The teacher told students that they were supposed to transform the sentence like this:

I had my room cleaned.

That made me wonder - don't we use causative to say that some sort of a professional service was done for us? If the agent who did something for me was my mum, it can't be in causative form, or am I wrong? In my opinion, this sentence could be transformed into a passive voice:

My room was cleaned by my mum.

I'm looking forward to your soon reply

'He went home from college once a week, to have his washing done'. This is OK (grammatically, at least ;-).)

Then I guess I was wrong. It simply didn't sound ok to me. Thank you ;-)

:-?I think it's a matter of what grammar books mean by causative.

• He had his trousers cleaned. Obviously causative.
• He had dirty trousers. [Obviously not]
• He had his trousers cleaned for him when the car drove through the puddle] [:-?]

In my view, intrention has to be involved.

PS It was a puddle of cleaning fluid, of course. ;-)

It can be. But it's a bit cheeky to say, "I had my mum clean my room".
